<span>After you solve a system of linear equations, you will get an ordered pair (x,y). Replace x with whatever number you obtained for x, and replace y with whatever number you obtained for y. If both your equations are true upon simplifying, you know it is correct.</span>

Answer:
s/8 = -8
s = - 64
Step-by-step explanation:
Solution
s/8 - 12 = -20 Add 12 to both sides
s/8 -12+ 12 = -20+ 12 Combine
s/8 = - 8 Multiply both sides by 8
8*s/8 = - 8*8
s = - 64
Answer:
y = 7 - 2x/3
Step-by-step explanation:
Make the y alone, so 3y = -2x+21
Divide everything else by 3, so y = -2x/3 +7
You end with the answer of y= 7-2x+3
